Full Description

1.1This test method covers the determination of the apparent viscosity of hot melt adhesives and coating materials compounded with additives and having apparent viscosities up to 200000 millipascal second (mPas) (Note 3) at temperatures up to 175C (347F).

Note 1:Although precision has not been studied, this procedure may be adaptable to viscosities higher than the present 200000mPas limit and temperatures above 175C (347F). Equipment described in this test method permits testing of materials having viscosities as high as 1610⁶ mPas and provides temperatures up to 260C (500F).

Note 2:For petroleum waxes and their blends having apparent viscosities below 15 mPas, Test Method D445 is especially applicable.

Note 3:One pascal second (Pas)=1000 centipoise (cP); one millipascal-second=one centipoise.

1.2The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
